SimpleXMLElementオブジェクトであるXML値を反復処理する方法

Question

XMLストリームがSimpleXMLElementオブジェクトに解析されていますが、使用可能なレコードをPHPページの値として繰り返し処理しようとしています。

[リスト]の親ノードは、テストXML（[0]とリスト[1]のリスト）の2つのレコードと同じ2倍です。 しかし、私はこれを "Basic SimpleXML PHPマニュアル

<?php 
    $xml = simplexml_load_file('http://feed.postlets.com/Burndog/6458ec1af54f632'); 

から用法」これは最初のリストのタイトル要素の値を提供するために動作します：

$value1 = $xml->listing[0]->title; 
    echo ' here:' . $value1; 

これは、利用可能な値を反復処理するために失敗します。

しますprint_rからの

foreach ($xml->listing->title as $title) { 
    echo $title; 
    } 
    ?> 

値：1以上があるよう

は、その後、それは絵のための要素をループに何を取るのだろうか？ ありがとう！

Answer 1

print_rの出力からわかるように、XML-Objectの 'listing'フィールドは、タイトルではなく配列です。これは役立つかもしれない

foreach ($xml->listing as $listing) 
{ 
    echo "Title: " . $listing->title . "<br>"; 

    foreach ($listing->photos->children() as $child) 
    { 
     echo $child . "<br>"; 
    } 
}
